The most detailed study of social media ever conducted.
The way people are using Twitter is changing in two respects. Firstly, it is becoming a passive source of discovery for users and secondly, users are using more as a tool or service rather than a pure social service. Amazingly, only 51% of active users claim to have posted a tweet in the past month. This means that half the active user base is just reading, reacting or using Twitter as a source of discovery. The caricature of the average Twitter user banally talking about what they had for breakfast is dying.
